Answer:
The practice of law, city planning, language, and lots more
Step-by-step explanation:
The Romans influenced a lot of things that we now use in the modern world. These were jus scriptum (written law) and jus non scriptum (nonwritten law) "The term unwritten law was strictly referred to customs, while written law represented literally all law based on any written source and evidence." (How has ancient Rome influenced European law?)
Other empires were impressed by the Roman cities. The Romans practiced planning of their cities, so they make sense. Every aspect of the Roman cities was planned out, as was every major city on Earth.
The Roman language Latin inspired many other languages that are still used nowadays. These include all of the "Romance" languages. These are French, Spanish, Italian, Portuguese, Romanian, and Catalan languages. (no, romance not being love)
